IMPROVEMENT IN LAMP-BURNERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern:

lamps adapted to the burning of kerosene, may also y be applicable toother kinds of lamps. t,

It consists, iirst, in elastic bearing-straps, of novel construction,for supporting thejournals ofdouble feedrollers, whereby provision ismade for reception between said rollers of wicks of' differentthicknesses.

It consists, secondly, in an elastic chimney-bolder, of novel character,whereby provision is made for the expansion of the chimney by heat.

Referring to the accompanying drawings'- Figures 1 and 2 representvertical sections of a lampburner constructed accordingto myimprovement, taken at right angles to each other; and

Figure 3 represents a plan view of' the same, with the chimney and theburner-cap removed.

Similar letters of reference indicate corresponding parts in the severalfigures.

A represents the upper part, or neck of the leser- -voir ot akerosene-lamp, and upon which is fitted my improved burner.

rEhe wick-tube B is of the ordinary construction, cX- cept that it ismade to extend somewhat higher, for the purpose of lcssening danger ofexplosion, by increasing the distance between the llame and the oilcontained in the reservoir.

D is an annular support, or gallery, for sustaining the burner-cap, andis supported upon bracesb, passing therefrom, and secured to thescrew-cap E:

Between this ring, or gallery D, and the screw-cap, is formed an annularspacec, whichv serves as a better means of vent or ingress of air to theHaine than the small perfor-ations heretofore used for that purpose.

This annular space c may be of -any breadth best suited to the size ofthe burner, and the degree oi' draught required.

O is a burner-cap, of conical, or tapering formation,`

and of a height proportionate to that ofthe wick-tube. The base of thisburner-cap is of suitable size for resting upon vthe face of the saidgallery D, and is, or

may be retained thereon by means of springs, e e, attached thereto, andfitting in recesses, .s s, made in the inner edge of thegallery, while,by its upwardlytapering form, the air is more rapidly drawn up to theflame aucharound the heated parts.

By means of this new construction of burners, a much stronger draught isobtained than with burners of ordinary construction, thereby not onlya'iording better light, by assisting combustion and saving oil byconsumption of gases otherwise escaping, but also by the more rapidcirculation of air in and around the heated parts of the-burnen'thetemperature of said parts is reduced, thereby rendering the lamp lessliable to explosion..

H is an elastic chimney-holder.

Said holder is composed of two pieces of elastic wire,

which-having their corresponding extremities arranged near each other,are each secured by their opposite extremities to opposite sides of thegallery l), and, extending upwardly, and incliningtoward each other, aremade to vcross ator about a point, x, and after crossing, are each bentoutwardly in opposite directions, so as jointly to form a horizontalelastic ring for the reception of the chimney, their central portionsbeing previously bent in a semicircular form for that purpose.

f f are curved elastic bearing-straps, attached to the screwcap E, andhaving elongated bearing-openings in them, forreception of the journalsof double feed- Tollers, m m.

By `means of'said curved elastic straps, whose forms in their normalstate are much more curved than when outwardly strained, as representedin the drawing, the said feed-rollers are not only held against thesides of the wick, but, by their yielding and contracting nature,provision is made for reception, between the rollers, of wicks ofdifferent thicknesses.

What l claim as my invention, and desire tohave secured by LettersPatent, is-

1. 'lhe curved elastic bearing-straps f f,.in combination with thedouble feed-rollers m m, substantially as and for the purpose herein setforth.

2. The elastic chimney-holder D, constructed as described, ior thepurpose herein set forth.
